Enrique Lomnitz; Through the work of his organization, Isla Urbana, Enrique Lomnitz
aims to solve the water shortage in Mexico City by creating a sustainable system
based on rainwater capture systems.

“Poor people or rich people feel less strongly about
water- it is not about wealth, it is about water availability.” Enrique
Lomnitz, Director of Isla Urbana, tells our Capstone group
during our meeting with him in Mexico. Isla Urbana seeks to catalyze a revolution
in rainwater harvesting and works to ensure sustainable water supply for Mexico
city for people of all economic levels.[1]
Enrique is an entrepreneur and visionary. He is humble and
plays down his successes, though a badge that he takes pride in is being an Ashoka fellow.
In addition to becoming a part of a global network of social entrepreneurs,
being an Ashoka fellow adds credibility to his work and provides him with
financial support to help achieve his goals (for the next 3 years, at least).
Enrique also participated in Initiativa Mexico, a popular Mexican reality
TV program in 2011 that is about projects that have positive impact in Mexico.
With over 8,000 applications, Isla Urbana was one top 20 NGO’s chosen.
The organization has been named one of the top best-practice organizations by UN-Water for Life, they were finalists in
the 2010 BBC World Challenge competition, and
participate in making commitments at the Clinton
Global Initiative.
In Mexico City, millions of Mexicans are without adequate
access to water. The Isla Urbana programme of IRRI México
is dedicated to resolving the water crisis in Mexico City through the installations
of rainwater harvesting systems. Isla Urbana
designs, build and install rainwater harvesting collection systems for low
income peri-urban communities in Mexico City. They teach rainwater harvesting
courses, host and participate in community events, and are dedicated to making
Mexico City’s water management policy sustainable. They do all this working
household by household--ensuring decentralized water security--in a place known
to have serious water scarcity issues.[2]
“We got nothing to teach them we have everything to
learn.” Enrique tells our Capstone group, when referring to
working in low-income communities. The rain water harvesting, if implemented on
a large scale, can meet up to 50% of Mexico City’s needs.[3]
SUCCESSES AND STRENGTHS

In Mexico, I sat down with Rachel Smith of IRRI-Mexico
and Engineers
Without Borders UK. She worked on producing a report for Isla Urbana studying
the adoption rates of rainwater harvesting in Mexico D.F. last year and continues to work for IRRI-Mexico. “Water scarce
communities are knowledgeable of water conservation, Isla Urbana
expands on their knowledge to introduce their technology. And the government
has all the economic advantage – with our system, they save money” Rachel says when I ask her about Isla Urbana’s
strengths.
Isla Urbana addresses an immediate problem and provides an
immediate benefit. Since 2009, Isla Urbana have installed 1,151 systems, helped
12,862 people, and harvested 54,400,000 gallons of water.[v] “We
are sowing the seeds of a systemic solution,” Enrique says.
CHALLENGES
Amidst their successes, Isla Urbana also faces barriers
and challenges. Financing has been their biggest challenge, and what they would
like to do is to expand on their international funding. “We are weak in
financing, it would be great to open up internationally” Enrique admits. “We have
an international setting and an international team but we are not so
international in funding, with only over 4-5% percent of their funding coming
from abroad” Enrique adds.
"One of the main challenge for Isla Urbana is
overcoming the entrenched preconception about water management in general"
Rachel stresses. Isla Urbana is developing a sustainable business model, in the
context where water is heavily subsidized. The “Pipa’s,” otherwise known as water-trucks,
and grid water are subsidized by the government. “It is a challenge to get
people to get people to pay for the rainwater harvesting systems if they don’t
have the concept that water costs a lot” Rachel adds.
The government, as part of their push to improve water
supply, funds groups of households that do not have good grid connection and
where water-trucks do not come as often to receive Isla Urbana systems. This
improves their water supply resilience. Where there is more water supply, there
is less scarcity. The government has also paid for Isla Urbana systems in
households, without the households contribution. “Reliance on government could
sometimes be detrimental,” Rachel says, “by doing so, it encourages reliance on
government funds rather than developing private sector model of business
selling product/services. The further out you get (of the urban periphery),
people illegally tap into the water line. This only means that the value of
water is not reflected in the price that people pay.”
“My expectations are not
super specific” Enrique says tells our Capstone group in our interview with him
when we asked him of his expectations from our team. “I hope to gain insight or
ideas into Isla Urbana from people that come at this from different disciplines
from what our team has (2 industrial designers, 2 engineers, 1 anthropologist,
1 urbanist, 1 linguist and 5 plumbers). It would be amazing to get some
help developing better ways to measure actual and potential impact, especially
on an economic level, as the systems start to scale up” he adds.
“We are working to
develop rainwater harvesting towards its fullest potential in Mexico, yet we
are not even sure of the real number of houses that could easily be fitted with
rainwater systems in the city. We know there are lots, but we have little
in terms of numbers” Enrique explores. “It would be amazing to start
building a map of the potential, in numbers and general (physical) areas with
most potential. If we can start mapping this better, we can start really
calculating interesting things like how an investment in rainwater harvesting
(RWH) considered here as investment in water infrastructure (this is important
because the way the water subsidies work means that the real economic winner
when someone saves water through RWH or any other method is the government).
If we can start mapping all this, we can start calculating future water
stress scenarios and how much relative good would be done if you already had X
number of RWH systems deployed and working in the city. This kind
of stuff is very, very interesting to me and could be really useful as we argue
the value and potential of RWH to people at higher and higher levels.” Enrique
adds.
That is where our
Capstone group comes in: to help Isla Urbana produce arguments, as it is
conceived, and build a tool of persuasion. Especially in helping them make a
persuasive case to government officials that Rain Water Harvesting Systems can
alleviate water infrastructure issues and deliver a reliable source of potable
water. In doing so, our Capstone group first asks ourselves whether
or not it was possible to map informal development patterns in Ajusco where
Isla Urbana operate. As our research progresses, our goal is to deliver a
map that is structured in such a way that information can grow with it. In
our first meeting with Enrique in Mexico, we had identified the building blocks
of information that could grow with this, such as political boundaries,
pollution, and numbers of housed in each types of section.
ISLA URBANA CAPSTONE VISIT IN MEXICO
Pictures from our Isla Urbana Workshop in Mexico
The day after our
Capstone group’s arrival in Mexico, Helene Gutierrez of IRRI-Mexico met our Capstone group
in our hotel. She assisted us to the Isla Urbana
headquarters in Ajusco, an hour drive from where we have stayed in Condessa.
Ajusco is a 3,930 m lava dome volcano located just south of Mexico City and it
is the highest point in the Mexican Federal District. Our mapping work focuses
on the urban area Ajusco that is filled with medium systems Tlalpan rainwater
catchment systems. This area, urbanized informally on the slopes of Ajusco,
suffers from severe water shortages. The houses often go weeks without water
and when they do receive water it is of poor quality, with some areas
completely lacking the water service. “The lack of good water supply forces
many families to buy water pipes, and the costs associated with these can
become very high. These usually have people in a state of unsecured draining
water access. The only good thing is that, thanks to the shortage, this area
has developed a true culture of caring and valuing water” Rachel explains.

We visited Ajusco to get
a good sense of the community, we visited homes in Ajusco that these rain water
harvesting systems were installed in, experienced how Isla Urbana is like in
the field, and studied the mechanics of system. Unfortunately, we were unable
to install rainwater harvesting systems, however, we were able to meet Carmen.
During rainy season many IU systems don’t use grid or trucked water, or “Pipa”
as it is known in Mexico. At this time, residents use RWH during rainy season.
Thankfully, there is a way that Carmen can maintain self-sufficient and
sustainable access to clean water.[5]

GOAL
Enrique’s vision for
Isla urbana is to “catalyze a process, that can be at it’s best full-bloom in
40 years.” In generating a movement in the city and country with rainwater
water harvesting systems, they hope to replicate this idea in other places
where needed. In our capstone contribution, we can help their goal by
developing a tool that would allow Isla Urbana to plot and predict potential
impact that filling up a region that rainwater harvesting systems would have.
ATTENTION: On the 6th of April, Earth
Institute will be hosting a Sustainability Seminar with Alex Eaton, Sistema
Biobolsa's Director, as their guest. Entitlted, IRRI Mexico:
Entrepreneurship and Projects for Local Sustainable Solutions, Alex
will be joined by Enqirue Lomnitz, Director of Isla
Urbana. This seminar will be held from 11:00am - 5:00pm at
the International Affairs Building (IAB) – Altschul Auditorium Room Room
#417. Please RSVP for this event HERE.
Special thanks to Rachel and Enrique for taking the time to be interviewed for this blog!
